Layered Packages

The Fedora IoT images utilize rpm-ostree which is a hybrid image/package system. This allows layering a package on an existing image which produces a new versioned deployment. Similarly, removing a layered package creates a new versioned image. The rpm-ostree utility keeps two deployments available so a rollback procedure can be used to revert to a previous deployment.
